It is contained in high protein foods, such as poultry, eggs, dairy, pork, and grains too. It is a precursor to glutathione in our livers, an essential antioxidant. It also participates in protein synthesis in tissue repair. It is a crucial amino acid from these two perspectives. ...Read more

Reference range value of homo-cysteine blood test report is 8-20 mg/dl. Does anyone know about any similar or same reference range value? Thank you.

Reference range value of homo-cysteine blood test report is 8-20 mg/dl. Does anyone know about any similar or same reference range value? Thank you.

Ranges vary: Reference ranges for homocysteine vary some from lab to lab. Most physicians today set little by this number, as an atherosclerosis risk or otherwise, unless it is very far above the upper limit you've cited. Of your many listed problems, the one that concerns me is papilledema / blurry vision; i'm concerned you have pseudotumor cerebri and this vitamin ; lab test stuff diverts the investigation. ...Read more

Could you please advise about exact medical laboratory term for homo-cysteine with methionine loading test? Thank you.

Could you please advise about exact medical laboratory term for homo-cysteine with methionine loading test? Thank you.

See the link: http://www.ncbi.nlm.nih.gov/pubmed/16957558 homocysteine is measured after methionine loading. This has been a controversial test for two decades; the claim is that it reveals an additional coronary risk factor, though what is to be done about this isn't clear at least to me. Others may have ideas to share. http://vmj.sagepub.com/content/7/1/29.full.pdf (recommends "research only"). ...Read more

H-cysteine is 14.78 mg/dl or 109.32 mmol/l, while B12 serum count is 352 pg/ml. Majority B12 def. Symptoms for too long. How would you interpret this?

H-cysteine is 14.78 mg/dl or 109.32 mmol/l, while B12 serum count is 352 pg/ml. Majority B12 def. Symptoms for too long. How would you interpret this?

Need B12: It is optimal to have a B12 level of 500 or above. Anyone with a B12 below 500 who has symptoms or signs of B12 deficiency should take methylcobalamin, either sublingual or im, in doses sufficient to raise levels above 500. You may also need the l-5-mthf form of folate, (folic acid) b6 ; trimethylglycine to lower homocysteine below 10. See http://bit.Ly/1607tg3 ; http://bit.Ly/jxwxd2. ...Read more

High: "Homocysteine at 1 – 5 ?mol/L has been found to specifically block tissue plasminogen activator, but not plasminogen binding to endothelial cells. Homocysteine concentrations as low as 8 ?mol/L dramatically increase the affinity of lipoprotein(a) for plasmin-modified fibrin surfaces, thus inhibiting plasminogen activation." from: The High Atherosclerotic Risk Among Epileptics ...Read more

Should I take N-acetyl cysteine before or after drinking alcohol and much should I take? Same question for Milk Thistle.

Should I take N-acetyl cysteine before or after drinking alcohol and much should I take? Same question for Milk Thistle.

Do not take any: Alcohol is a poison that never did anybody any good, ever and you should not take it. What do you want to take milk thistle for? None of these things, including N-acetyl cysteine is going to do you any good and there only potential for harm.

Other side effects include nausea, vomiting, and diarrhea. Although it often chelates metabolites in the liver, it can cause liver toxicity and should be avoided if you have liver issues, take numerous medications or drink frequently ...Read more

Impaired are: tyrosine to dopamine, tryptophan to niacin, cystathionine to cysteine. Which cofactor and vitamin is common to all three pathways? Ty

Not an easy answer: These pathways can be impaired due to a primary disorder or secondary to other conditions interfering with metabolic pathways. Until a thorough investigation has been done, it is not likely that you will find a simple solution or single co-factor that will treat your biochemical imbalances. ...Read more
